I have been reviewing close votes suggestions for maybe half an year, already (I am currently at about 700 close votes suggestions examined). Until maybe a month ago there were always less than 80 suggestions to examine (subjective estimate, base on memory). Lately, though, I often find >150 suggestions in the queue and I would like to know why:
have the persons having acces to site analytics noticed a sharp increase in the number of questions and accounts in the last month or so?
are fewer users getting involved in reviewing activities, so the same burden as before falls on the shoulders of fewer people?
have users recently become more involved in curating the site by flagging more questions and answers for closure or deletion?
Have you noticed the same thing? Are there other explanations of it? Strangely, the number of first posts, low quality posts, reopen votes and late answers seems to have stayed constant.
